0 amp draw means the AC is running without consuming any electricity? It's just a gimmick by the company to sell more ACs and they will be very successful no doubt, because unfortunately we tend to believe in magic more than science.
Even if the compressor completely shuts off, at the very least, the blower motor will still be running and that will consume about 0.25 amp. And the blower motor does not cool the room, it just moves the air.
If you want to know real power draw, put a multimeter on the live wire when the compressor is running.
